About the role (from employer)

Who We Are

At OKX, we believe that the future will be reshaped by crypto, and ultimately contribute to every individual's freedom.
OKX is a leading crypto exchange, and the developer of OKX Wallet, giving millions access to crypto trading and decentralized crypto applications (dApps). OKX is also a trusted brand by hundreds of large institutions seeking access to crypto markets. We are safe and reliable, backed by our Proof of Reserves.
Across our multiple offices globally, we are united by our core principles: We Before Me, Do the Right Thing, and Get Things Done. These shared values drive our culture, shape our processes, and foster a friendly, rewarding, and diverse environment for every OK-er. OKX is part of OKG, a group that brings the value of Blockchain to users around the world, through our leading products OKX, OKX Wallet, OKLink and more.

About the Opportunity

We are looking for an experienced blockchain developer to join our team building the next generation of high-performance on-chain trading infrastructure. You will help design and implement a unified trading engine — supporting Perpetuals, Spot, and Prediction Markets under a single margin account — and contribute to ExchangeOS, an infrastructure layer that lets KYC'd institutions and Web3 entities stake to create and operate their own trading venues (DEXs) on top of our chain.
 

What You’ll Be Doing

  1. Design and build a unified account and matching system that supports Perpetuals, Spot, and Prediction Markets — including on-chain order matching, cross-margin validation, settlement, and liquidation/risk engines (ADL, ADL-avoidance, ADL waterfall, ecosystem insurance fund mechanics).
  2. Build and optimize the core components of ExchangeOS: the staking/venue-creation framework that allows KYC-verified institutions and Web3 protocols to launch and operate their own dex on shared infrastructure.
  3. Drive performance engineering across the stack — parallel transaction execution, low-latency order pipelines, and throughput/latency optimization at the engine and chain level.
  4. Track cutting-edge blockchain and trading-system technology (e.g. Hyperliquid, dYdX, other high-performance perp DEX architectures) and apply best practices to our infrastructure.
  5. Partner with product and business teams to translate venue/exchange requirements into technical designs, and provide ongoing technical support.
 

What We Look For In You

  1. Strong proficiency in Rust, with hands-on experience in high-performance, low-latency systems; experience with parallel/concurrent execution engines is a strong plus.
  2. Deep understanding of exchange/matching engine mechanics: order book design, margin systems, liquidation and ADL, settlement, and risk engines — familiarity with perpetual, spot, or prediction market products is a strong plus.
  3. Solid grounding in blockchain fundamentals (consensus, P2P networking, cryptography); experience reading core code of major L1/L2 systems (Ethereum, Optimism, Arbitrum, or high-performance L1s like Hyperliquid/Solana) is a plus but not the primary focus of this role.
  4. Strong systems-performance mindset: profiling, memory/allocator tuning, and designing for sub-millisecond latency at scale.
  5. Excellent teamwork, communication, and logical reasoning skills; genuine passion for trading systems and blockchain technology. 

Perks & Benefits 

  • Competitive total compensation package
  • L&D programs and Education subsidy for employees' growth and development
  • Various team building programs and company events
  • Wellness and meal allowances 
  • Comprehensive healthcare schemes for employees and dependants
  • More that we love to tell you along the process!

StanChart, Circle, Ripple back crypto exchange OKX at unchanged $25bn valuation

Crypto exchange OKX has secured strategic investments from Circle, Ripple, QRT, and SC Ventures at a $25 billion pre-money valuation to accelerate its expansion into real-world asset tokenization. This funding round, which extends a previous investment led by Intercontinental Exchange, aims to provide the capital necessary for OKX to scale its tokenized product offerings. The exchange has already integrated significant RWA features, including the listing of over 40 tokenized U.S. stocks and ETFs for non-U.S. and non-European clients. Furthermore, OKX recently announced the launch of a tokenized securities venue utilizing SEC exemptions to facilitate regulated trading. By leveraging partnerships with major financial players like Standard Chartered and Circle, OKX is positioning itself as a bridge between traditional finance and blockchain-based markets. The inclusion of Ripple and its RLUSD stablecoin further signals a strategic focus on cross-border liquidity and asset settlement. This development highlights a broader industry trend where centralized exchanges are aggressively pivoting toward institutional-grade RWA infrastructure to diversify revenue streams beyond volatile crypto assets.

The Coming Wave of Tokenized Stocks in U.S. Markets

Tokenized stock trading is emerging as a transformative force in U.S. equity markets, promising to bridge the gap between traditional finance and blockchain technology. Platforms like OKX are exploring pathways to offer tokenized equities by leveraging SEC exemption frameworks such as Regulation A+ and Regulation D. This approach aims to bypass burdensome full registration processes while maintaining the strict compliance standards required by the SEC. The integration of these assets could enable 24/7 trading and automated asset management, reflecting a broader market appetite validated by institutional interest from firms like BlackRock. However, significant challenges remain regarding custody, the management of corporate actions like dividends, and the need for robust regulatory alignment. Startups must navigate a competitive landscape against legacy exchanges while ensuring their technological infrastructure meets stringent oversight requirements. Success in this sector depends on the ability to harmonize decentralized finance liquidity with traditional regulatory mandates. Ultimately, the evolution of tokenized stocks represents a potential seismic shift in how investors access and manage equity portfolios within an integrated financial ecosystem.

OKX, NYSE Parent ICE Seek US Tokenized Stock Trading Platform, Starting With 63 Shares

OKX and Intercontinental Exchange (ICE) have formed a joint venture, OKXICE LLC, to launch a platform for trading tokenized stocks in the United States. The venture has filed paperwork with the SEC to tokenize and trade shares of 63 companies currently listed on the New York Stock Exchange. This initiative leverages a new SEC “innovation exemption” that permits blockchain-based securities to trade under specific regulatory conditions, including a 30-day issuer objection period. By combining OKX’s blockchain infrastructure with ICE’s market technology, the platform aims to enable 24-hour global stock trading while maintaining standard shareholder rights like dividends and voting. This move represents a significant institutional push to modernize equity markets through smart contracts and liquidity pools. The development signals a shift in the US regulatory landscape, potentially intensifying competition among firms seeking to bridge traditional finance with distributed ledger technology. As one of the first entities to utilize this new SEC framework, OKXICE sets a precedent for how legacy exchanges and crypto-native firms can collaborate on regulated RWA products.
